This is the essence of human beings. If there is good, there will be evil, but the human heart also has a steelyard. Whether you are good or evil determines that you face the world with various faces in society. People are thoughtful, so people are fickle. If you don't know a person, you won't know whether he is good or bad to you. You can't know a person by his appearance. One Buddha and one magic are all in one thought, and whether you become a Buddha or a magic is formed in one thought. Don't look at a person with colored glasses, because you have no idea what kind of person he is.
